模型信息
中文名称:HIV CCR5-tropic静脉途径感染人源化BLT小鼠模型
英文名称:HIV CCR5-tropic intravenously infected of humanized BLT mouse model
类型:艾滋病毒动物模型
分级:NA

研究背景
来源文献:Generation of HIV latency in humanized BLT mice.
PMID:22013053
DOI:10.1128/JVI.06120-11
制备方法
Briefly, preconditioned NOD/SCID-gamma chain null (NSG) mice (The Jackson Laboratories) implanted with thymus and liver tissue (Advanced Bioscience Resources) were transplanted with 2×10^5 to 3×10^5 autologous human fetal liver CD34+ cells and monitored for human engraftment.Humanized BLT mice are susceptible to vaginal, rectal, and intravenous HIV infection (10– 12, 36). We infected BLT mice with CCR5-tropic HIV (JR-CSF or SF162). Infected BLT mice received ART consisting of daily intraperitoneal injections of emtricitabine (FTC; 140 to 200 mg/kg body weight), tenofovir disoproxil fumarate (TDF; 146 to 208 mg/kg), and raltegravir (RAL; 56 to 80 mg/kg). BLT mouse that received ART for 58 days (followed for a total of 77 days postexposure) as well as in a pair of untreated, infected BLT mice (followed for a total of 69 and 70 days postexposure).
评价验证
诊断:血浆病毒血症。
生物安全性
所有感染动物必须在ABSL-3室中进行。
讨论与结论
1.该模型制备比较成熟,国内外都有此模型,构建和评价指标一致,所以该模型应用广泛,具有统一的操作规程。
2. 该模型制备的关键:1)小鼠必须是重度免疫缺陷的,而且饲养环境必须洁净;2)HIV操作需要生物安全。
3.此模型具有完善的人的免疫系统,HIV感染后,具有艾滋病病人相似的临床症状,所以具有很高的比较医学应用价值。
